Analysis and Prevention Strategy of Typical Grounding Faults in Substation Direct Current System
Station direct current system is an important part of substation,which provides stable direct current power supply for relay protection devices,safety automatic devices and other equipment.However,the direct current system in substation is prone to direct current grounding fault,which affects the power supply of equipment and endangers the safe operation of power system.This paper analyzes the typical grounding faults of direct current system in operating substations and substations under construction,finds out the crux of the faults and puts forward corresponding preventive measures to reduce the probability of direct current grounding faults and ensure the reliable operation of direct current system.
